Verified Answer
Pranav walked at 5 kmph for certain part of the journey and then he to...
Total distance = 17*10 = 170
Let Journey travelled by auto in x hr
25 * x + (10-x ) 5 = 170
25 x + 50 – 5x = 170
x = 6
Required Distance = 6 * 25 = 150 km

Pranav walked at 5 kmph for certain part of the journey and then he to...
Given information:
- Pranav walked at 5 kmph for a certain part of the journey
- Pranav took an auto for the remaining part of the journey travelling at 25 kmph
- The average speed of the entire journey is 17 kmph
- The total time taken for the entire journey is 10 hours
To solve the problem, we can use the formula:
Average speed = Total distance / Total time
Let's assume that Pranav traveled a distance of x km by walking and (D-x) km by auto. Here, D is the total distance of the journey.
Using the formula, we get:
17 = D / 10
=> D = 170 km
Now, we can use the formula:
Total time = Time taken to walk + Time taken by auto
=> 10 = x / 5 + (D - x) / 25
Simplifying the above equation, we get:
=> 50 = x + 5(D - x)
=> 50 = 4x + 5D
Substituting D = 170 km, we get:
=> 50 = 4x + 5(170 - x)
=> 50 = 5x + 850
=> 5x = 800
=> x = 160 km
Therefore, Pranav traveled 160 km by walking and (170 - 160) = 10 km by auto.
Hence, the answer is option (C) 150 km.
- Pranav walked at 5 kmph for a certain part of the journey
- Pranav took an auto for the remaining part of the journey travelling at 25 kmph
- The average speed of the entire journey is 17 kmph
- The total time taken for the entire journey is 10 hours
To solve the problem, we can use the formula:
Average speed = Total distance / Total time
Let's assume that Pranav traveled a distance of x km by walking and (D-x) km by auto. Here, D is the total distance of the journey.
Using the formula, we get:
17 = D / 10
=> D = 170 km
Now, we can use the formula:
Total time = Time taken to walk + Time taken by auto
=> 10 = x / 5 + (D - x) / 25
Simplifying the above equation, we get:
=> 50 = x + 5(D - x)
=> 50 = 4x + 5D
Substituting D = 170 km, we get:
=> 50 = 4x + 5(170 - x)
=> 50 = 5x + 850
=> 5x = 800
=> x = 160 km
Therefore, Pranav traveled 160 km by walking and (170 - 160) = 10 km by auto.
Hence, the answer is option (C) 150 km.
